Sina Madani commented on SPARK-650:
-----------------------------------
I too have this problem. It seems that Apache Flink solves this quite nicely by
having "RichFunction" variants for operations like map, filter, reduce etc. A
RichFunction, such as RichMapFunction, provides open(Configuration parameters)
and close() methods which can be used to run setup and teardown code once per
worker and also initialise the worker from primitive key-value pairs.
> Add a "setup hook" API for running initialization code on each executor
